The median is the value of the middlemost observation(s). The median is to be calculated only after arranging the data in ascending order or descending order. The mode of statistical data is the value of that variate which has the maximum frequency. The mode for ungrouped data is the value that occurs most often. The […]
A line that intersects a circle at two distinct points is called a secant of the circle. A tangent to a circle is a line that intersects the circle only at one point. The common point of the circle and the tangent is called the point of contact. A tangent to a circle is a
A set of mn numbers arranged in the form of a rectangular array of m rows and n columns is called an m x n matrix. Each number or entity in a matrix is called its element. In a matrix, the horizontal lines are called rows, whereas the vertical lines are called columns. If a
The mutual perpendicular lines intersecting each other at their zeroes are called rectangular axes or coordinate axes. The horizontal axis is called the x-axis and the vertical axis is called the y-axis. (0,0) is called the origin. The position of a point in a plane is expressed by a pair of two numbers called coordinates.
